Water proofing admixtures specialized in preventing concrete from water penetration. Concrete absorbs water, because there are capillary suctions within the hydrated cement paste that form due to surface tension in the capillary pores. How active water proofing admixtures are? It …

Concrete admixtures are not the essential component of the mix, but nowadays their use in concrete is increasing very rapidly and their importance is becoming more valuable. A concrete mix without admixtures is an exception in this real world and …

Anti bacterial admixtures are used against organisms like insects, fungi or bacteria that affects the property of concrete. Bacterial affect is not minor effect to concrete, but they affects very adversely. Organisms release corrosive chemicals through their metabolic action on …

Mineral admixtures and chemical admixtures are the extra ingredients other than water, cement, aggregates and fibers. These are added to the concrete batch plant during batch mixing or at the start when other quantities are added. Admixtures offer very favorable …

Mainly water reducing admixtures are divided into two categories depending upon the amount of dose being use in concrete and in result the decrease in the required weight of water. Low range plasticizers or regular plasticizers High range or super-plasticizers …

A type of chemical admixtures that are used as a replacement of water is known as water reducing admixtures. By using that kind of admixtures, amount of required water for a workable concrete will be reduced and hence improved the …

Air entraining admixtures affect the strength of concrete up to large extent. Air entraining admixtures have almost 15-25% effect on strength as compared to normal concrete. By using air entraining admixtures strength of concrete diminishes.

A place where weather is not normal (abruptly changing), air entraining admixture is used that protects concrete from different weather actions. Concrete is very weak against frost action in this water penetrates into concrete and damages the concrete.
